Issue executing PublishAzureDevOpsExtension using VsTeam

[learner-1111]

I have the following task:

• task: PublishAzureDevOpsExtension@4
  displayName: 'Publishment}} Extension'
  inputs:
  connectedServiceName: 'someServiceName'
  fileType: vsix
  connectTo: VsTeam
  vsixFile: $(Agent.BuildDirectory)/drop/dev/*.vsix

We are trying to publish a react js based custom extension to a private marketplace. However, we keep getting the following error message:

"error: TypeError: Cannot read properties of null (reading 'versions') "

I am trying to google the error message and most results are npm and react related build. However we have done the built successfully and produce the vsix file in the previous stage before executing the task above using the following azure devops steps:

- script: npm run build-and-package
  displayName: 'Building and Packing extension'

- task: CopyFiles@2
  displayName: Copy vsix files
  inputs:
    sourceFolder: $(Build.SourcesDirectory)/out
    contents: |
      **/*.vsix
    targetFolder: '$(Build.ArtifactStagingDirectory)'

Any clues the source of the issue for the "error: TypeError: Cannot read properties of null (reading 'versions') " error message? thanks!

Hi @learner-1111 thanks for reporting!
We are working on more prioritized issues at the moment, but will get back to this one soon.

This happens on first publish, because there are no versions returned from the API. However, the CLI expects versions to always be populated.

tfs-cli/app/exec/extension/_lib/publish.ts

Line 370 in 9f0c37e

const versions = ext.versions;

A workaround is to use the --no-wait-validation flag.
